LG WebOS TV Update HA 0.104.2 Numpy Error

Configuration
1

I have made the changes that is required since the way of integration of webostv has changed. But im getting a config error:

Component error: webostv - 

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy c-extensions failed.
- Try uninstalling and reinstalling numpy.
- If you have already done that, then:
  1. Check that you expected to use Python3.7 from "/srv/homeassistant/bin/python3.7",
     and that you have no directories in your PATH or PYTHONPATH that can
     interfere with the Python and numpy version "1.18.1" you're trying to use.
  2. If (1) looks fine, you can open a new issue at
https://github.com/numpy/numpy/issues.  Please include details on:
     - how you installed Python
     - how you installed numpy
     - your operating system
     - whether or not you have multiple versions of Python installed
     - if you built from source, your compiler versions and ideally a build log

- If you're working with a numpy git repository, try `git clean -xdf`
  (removes all files not under version control) and rebuild numpy.

Note: this error has many possible causes, so please don't comment on
an existing issue about this - open a new one instead.
Original error was: libf77blas.so.3: cannot open shared object file: No such file or directory

So, how can I uninstall and reinstall Numpy (whatever it is) ?
Thanks to anyone that could help on this.

This worked for some, but did not work for me… Still searching for a solution.
(VENV in a Pi3)

After the above command, I still got the error, but with a different “original error”, that was:

Original error was: /lib/arm-linux-gnueabihf/libm.so.6: version `GLIBC_2.27' not found (required by /srv/homeassistant/lib/python3.7/site-packages/numpy/core/_multiarray_umath.cpython-37m-arm-linux-gnueabihf.so)

Then I solved it running the following command inside the VENV:

pip3 install numpy --no-cache-dir --force-reinstall --no-binary :all:

Now the “check config” returns no error but at the same time after restarting HA it does not appear the entity to pair the WEBOSTV, so there is still something wrong. It is now beyond my knowledge. Any help is welcome. Thanks.

OS: I know the config webostv: is correct, since it worked with another instance of HA (hassio) that I use for testing purposes only, but it is not for production…
